OF WASHINGTON, DISTRICT OF COLUMBIA.

IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 120,214, dated October 24, 1871.

To all whom it may concern:

' Be it known that I, SAMUEL Ross, of Washington, in the District of Columbia, have invented a certain Improvement in Lamp-Burners, of which the following' is a specification:

This invention relates to the class of burners the wick-tube of which is in part surrounded by a short tube for the purpose of inducing an upward current of air in close proximity to said wicketube to keep it at a low temperature; and my improvement consists in the peculiar shape of this short air-tube and its arrangement within a cylindrical aperture in the perforated ilange by which it is suspended, whereby two crescentshaped openings are left in the flan ge, one upon each of the flat sides of the air-tube, to permit a large body of air to pass directly from the perforated basket to the flame 5 the object being' to provide for a more perfect combustion of the hyi drocarbon, as well as a betterl means for keeping the wick-tube cool.

Figure 1 is a sectional elevation of my improved burner. Fig. 2 is a* top view of the airtube and its flange. Fig. 3 is a bottom view of the same. Fig. 4. is a transverse vertical section thereof.

The same letters of reference, where employed, indicate identical parts.

A refers to the wick-tube, extending a suitable length from each end of the hollow screw-cap A', which screws into the neck of the lamp-bowl. The upper exterior end of the wick-tube is surrounded by a perforated basket, B, and the ordinary slotted deflector, C, which terminates at the lower end in the chimney-base D, and is hinged to the basket in the ordinary manner. The air-tube is suspended within the deliector and basket around the wick-tube by a circular disk, E, resting upon a bead on the basket, and which is fastened to the air-tube about midway between the ends ofthe same, as shown'in Figs. 1 and 4.. The end of the air-tube above the disk or liange E, marked F, is made with parallel sides and rounded ends, as best seen in Figs. 2 and 3, so as to conform to the shape of the wicktube, between which and the air-tube is only a narrow space upon all sides for the passage of the air, which is thus brought into close contact with the wick-tube. Below the disk or flange E the air-tube is gradually drawn outward at the sides, so as to make it funnel-shaped, `with an elliptical throat, as seen in Figs. 2 and 3, this part of the tube being marked F. The air-tube is soldered or otherwise fastened at its rounded edges to the'edges of a cylindrical aperture, E', inthe disk E, so as to leave upon each of the iat sides of the air-tube a crescentshaped opening, c, in the disk. The latter has also numerous perforations in it for the passage of air in line jets.

That I claim as my invention, and desire to secure by Letters Patent, is-

The herein-described air-tube, composed of the parts F F', constructed as set forth, and perforated ange E, with crescent-shaped openings e e, substantially as specified.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses.
